I know most of us new about the event for 10.2.1, but this is the first I heard of this event for BES10.
Nice work BlackBerry, I think media events like this all over the world will really help the brand, keep moving.

I don't know, ill take your word for it though!
I just haven't herd of them actually doing walkthroughs and showing off what BB10 or Bes10 can do a media events.
I don't think I seen a Os update event other then when they introduced BB10. I don't keep up with all the news so I could be way off.
